>> announcer: this 'tis the "cbs overnight news." welcome to the "overnight news." leaders of the 28 nation european union continue their emergency meetings in brussels on the heels of britain's vote to leave. it was all smiles and handshakes for the eu family photo, but that didn't last long. leaders of germany, france and italy want the political divorce to get under way immediately. but outgoing british prime minister david cameron wants to leave that to his successor. meanwhile, cameron was disinvited to today's talks. mark phillips reports from brusselss. >> reporter: well the brexit battle moved to brussels and a new level of vitriol, if the hope this would be a civil, polite divorce.

it hasn't started that way. fresh from his humiliating appearance in parliament yesterday, a chastened david cameron who comes to brussels to meet with eu leaders he promised if they made concessions with britain on how tightly it would have to follow the e.u. rules he could deliver a stay in vote. he was wrong. as jean claude juncker showed he is not very happy with the brexiters at all. >> the british people voted on exit -- >> reporter: there was plenty of anger to go around including from brexit campaigner, nigel farage. >> i know that virtually none of you have ever done a proper job in your lives. >> reporter: cameron says it is up to britain to call in the lawyers and start divorce, article 50 of the e.u. treaty. >> the british government will not be triggering article 50 at this stage. before that we need to determine

the kind of relationship we want with the e.u. rightly something for the next prime minister and their cabinet to decide. >> reporter: and the next prime minister, boris johnson, the current front-runner is stalling. the leave side doesn't seem to have to worked out the playbook for its drive to departure. anyway it takes two to tango. and european leaders like angela merkel and francois hollande have their own reason to streak up the divorce music. the wave of populist e.u. movement that spread from britain to countries has taken heart from the u.k. decision. the e.u. establishment does not want to encourage them offering britain a quick, easy sweetheart deech deal. there is a lot mr. at stake here than who gets the record collection. access to the e.u.'s tariff-free single market comes with strings. particularly the provision for the free movement of labor across borders. and a promise to control its own immigration was at the heart of the leave campaign's pitch in

britain. as with any separating couple, the desire for an amicable divorce really survives the first shot across the negotiating table. this is a two-day meeting that's been organized here and david cam r cameron uninvited from the second day. >> after two years and $7 million, the house committee on benghazi issued its report. and hillary clinton is breathing a sigh of relief. clinton was secretary of state at the time of the terror attack in libya that left four americans dead. but the investigation found no new evidence that she did anything wrong. the investigation concluded that u.s. military forces stationed in europe could never have gotten to libya in time to stop the assault. but the committee was harshly critical of the pentagon, cia, and the state department, for leaving u.s. personnel unprotected. clinton is anxious to get the whole matter behind her and concentrate on the fall campaign. she rolled out a potential runningmate this week. massachusetts senator elizabeth warren.

nancy cordes reports. one joint campaign event with clinton was enough off to put elizabeth warren in the gop cross hairs. >> you want to see goofy? >> reporter: the senator and donald trump have been trading insults for weeks. monday, he called a sellout for backing clinton who she once criticized as too close to wall street. >> she has taken money from the groups and more to the point, she worries about them as a constituency. >> trump also brought up as he has before, warren's past claims that she is part native american. >> pocahontas. this time he told nbc news that warren "made up her heritage" which i think is racist. i think she is a racist. former massachusetts senator scott brown, who was defeated by warren in 2012, said she should take a dna test to clear up the controversy. and called her appearance with clinton uncomfortable. >> hillary has brains, she has

guts, she has thick skin. >> warren is one of many democrats vetted for vp. a source familiar with the process tells cbs news she is one of the clinton campaign's top picks. >> i do just love to see how she gets under donald trump's thin skin. >> reporter: cincinnati social worker, sue buenavites loved the idea of an all female ticket. >> yes, why not? i believe in girl power. >> teacher wanda brown wasn't getting her hopes up. >> i don't think america is ready for two women on the same ticket. i don't believe it. >> are you ready for it? >> i am. been ready a long time. >> reporter: clinton said in a speech yesterday that she understand the polls show she has a trust problem. she says she has tried to figure out why that is and address it. but clearly things like the benghazi crisis and her e-mail practices have contributed to it. >> for the republicans, donald trump is dialing back his proposal to block all foreign muslims from entering the united

states. now, trump wants to block muslims from what his campaign describes as terrorist-seeking nations. major garrett reports. >> reporter: last december we all remember donald trump pro posed a blanket ban on muslim immigration until congress could, "figure out what the hell is going on." faced with sagging poll numbers and on seson to the ban, the question for trump now is what is happening to that ban? >> so would a muslim coming from scotland, great britain, have you tweaked your policy on that? that is a far cry from the comments in december. >> donald j. trump is calling for a tee tal, complete shutdown of muslims entering the united states. >> reporter: donald trump faced immediate criticism from gop rivals. >> i do not agree with his appropria proposal. >> we don't need more division and everybody who is a muslim isn't some terrorist obviously. >> trump stuck to the ban and staggering political effect.

>> i talked about the muslim. we have a tremendous problem. i said we have to study it and see. >> reporter: two weeks ago in a major foreign policy speech, trump dropped explicit references to banning muslim immigration and substituted vague anti-terrorism language. >> i will suspend immigration from areas of the world where there is a proven history of terrorism against the united states. >> trump moderated the policy even mr. even more a week later. >> threatens peaceful muslims across the middle east and the world. >> reporter: national polls show half of general election voters oppose trump's original plan. all this leaves the impression trump is retreating and it's unclear. trump loyalists offer few clues. >> it is a change if you knew what the ban was. >> he is concerned of muslims from terrorist seeking nations. >> reporter: trump's campaign is calling his plan a ban on immigration from terror nations. trump is also saying he wants to

exclude people who have bad thoughts. >> the "cbs overnight news" will be right back. your heart loves omega-3s. but the omega-3s in fish oil differ from megared krill oil. unlike fish oil, megared is easily absorbed by your body. megared. the difference is easy to absorb. toquicker than everybody.es, allyson felix needs to be to win at home, she needs to be quicker than... allyson: chloe! that's why allyson felix uses bounty. the quicker picker upper. bounty is faster and 2x more absorbent. bounty the quicker picker upper.

>> hey! >> reporter: like any good head coach -- pat summitt was quick to reprimand a ref. or motivate a player with her words. but often times she was more effective not with the word she used, but the look she gave. three second! >> summitt's competitive fire led to 9,000 career wins and 8,000 championships and made her an unparalleled champion. in 2012, president obama awarded summitt, the presidential medal of freedom. >> when a doctor told pat summitt suffered from dementia. he almost punched him. when a second doctor advised her to retire. she responded do you know who you are dealing with here? >> you have to want this game. >> reporter: she turned the vols into a juggernaut. pushed women's basketball on the national stage and elevated the popularity of women's sports. she led her teams to more victories than any coach to ever

walk the sidelines. more than duke's coach, and john wooden. but her impact on the game was undeniable even to her fiercest rival, uconn head coach, gino oreama. >> she had the foresight, vision, intensity level. she made it "hey, it is go kay for will tune stare you down on the sideline and be upset and show emotion." the basketball floor at tennessee now bears her name as does a plaza across the street. >> i want everybody to know how much i appreciate what's happened here today. and i don't think i will ever forget it. and i love you all. thank you. >> reporter: in 1998, charlie rose asked summit what motivated her. >> tiell me what it is about coaching that so turns you on and seems to be the thing that you were put here to do? >> the thing that i like so much about coaching is that i got to

teach on a daily basis, i get to influence, i get to listen. >> our new head coach, holly warlick. >> reporter: in 2012, a year after diagnosed with early on set dementia, summitt stepped down from coaching. >> at first i didn't want to think about it. but -- it's, it's, it's been something very good for me. >> how? >> just -- putting things out there. you know, not hiding anything. and you know, i think that -- that's the best way to go. >> reporter: with her retirement, pat summitt dedicated her life to fighting alzheimers through her foundation. the disease may have forced her out of the game, but within it her legacy lives on. >> any words of wisdom? >> i think these young ladies know exactly what to do.

>> yes, yes they do. >> the summer olympics in rio get under way in five weeks. and there are still major problems from construction delays to political upheaval to the zika virus. now you can add another potential landmine-- the doping control lab for the games has been shut down. ben tracy got a look inside before the lock was put on the door. >> reporter: this is rio's brand new $66 million doping control lab. >> will these machines be running 24 hours a day during the olympics? >> 24/7. >> reporter: francisco radler the lab's director. eager to show it off earlier this month, touting technology. >> how sophisticated is this doping lab? >> one can say it is the most sophisticated of every lab. which is something that has for the olympic games. >> reporter: now two weeks after we interviewed him the lab has been shut down. the world anti-doping agency, or wada made that stunning decision six weeks before the games

begin. saying it was due to nonconformity with the international standard for laboratories. wada will not provide any details on what exactly was wrong. >> it is a problem to have the lab being suspended less than two months before the games. but will be a bigger blow to have a lab in the games that's not technically perfect. >> reporter: doping control labs world wild are under increased scrutiny after the world anti-doping agency published a report, accusing russia of an elaborate government-run doping program including infiltrating the lab at sochi to help athletes cheat. russia's track & field team has been banned from competing in the rio games. >> if this lab is not reopened in time for the olympics, what kind of impact will that have on the games? >> if it is truly is not reopened. it is a disaster. don catlan ran doping control labs at salt lake city, atlanta olympics. if the rio lab remains closed

samples will be flown daily new a lab in the united states or europe. rio's lab was expected to process 6,000 samples during the three weeks of the games. >> nobody wants to do this. it is a real pain in the neck. >> reporter: even if this lab is back up and running, does it call into question their results when the games begin? >> unfortunately it does. >> rio's lab was also shuttle down before the 2014 world cup. but that was due in part to obsolete equipment which has since been replaced. in a statement the lab said, it asserts its excellency as well as ethics and technical capacity. but for now this once lauded lab is idle, another black eye for rio before the olympic caldron is lit. ben tracy, rio.

final test drive for the rocket scheduled to lift off in 201, propelling the orion capsule into deep space. before astronauts are sent to mars, nasa will have to find a way to feed them. it sent them to the desert to cook up a solution. >> reporter: this vast plain with dunes and centuries of unforgiving wind and little rain is mars on earth. the desert in southern peru is harsh, arid, as close as gets on our blue planet to the red one next door. scientists are trying to unearth the recipe for farming on mars. hauling two tons of sun baked soil to their cosmic kitchen a trip that takes two days. >> you brought back a lot of dirt from the desert. >> reporter: this dirt is the ingredient in a ground breaking test taking place in lima, peru. >> the very first experiments we are doing. we don't know how it will work

>> reporter: you are saying potatoes are resilient? >> yes they are very resilient. so they, you can grow them almost anywhere. >> reporter: almost is the key word. >> this is the soil from la jolla desert. don't have anything coming up here. >> reporter: what does that mean? >> well it probably means the soil is not ideal for potato. if you see the soil, almost like, it is very dusty, almost like a cement. so, when we, we water it becomes very compact. and it might be a problem for the seeds to push through that, get oxygen and things like that. >> reporter: when we visited the lima green house last month potato seeds planted in ideal earthly soil sprouted. but after two weeks, the seeds in the martian like dirt failed to break through. the scientists found the seeds didn't have room to breathe. and the dirt was simply too salty. so they'll give the next batch of seed more space by loosening up the soil, as well as drying other varieties of tubers that dent mind a lit skpl tra salt in

space x startup can do it in half the time with the new falcon heavy rocket. >> should be able to launch op in 2024 with arrival in 2025. the entrepreneur told "the washington post" this month his ultimate goal is a self sustaining city on mars. and for that, musk's martians will need food. later this summer, cruzy and his team will try growing poe day tees in chambers that simulate the harsh atmosphere. if the potatoes can survive that then they are hardy spuds. >> they are hardy spuds, yeah. >> he also shared a confession. when he was a kid he really wanted to grow up to be an astronaut. he may not have reached the heavens. his research could provide it to millions on earth where drought and climate change imperils so many. >> not just about mars? >> no, not just about mars. we have more earthly goals in mind. >> it seems like a big challenge?
